SPECIFICATION forming part of Letters Patent No. 347,806, dated August 24, 1886.

Application tiled June 3, 1886. Serial No. 203.988. (No model.)

To all whom it may concern.-

Beit known that I, IRA J. HUNT, a citizen of the United States, residing at Kalamazoo, county of Kalamazoo, State of Michigan, have invented a new and useful \Vheeled Cultivator,

of which the following is a specification.

This invention relates to that class of cultivators,nsed in harrowing the field and cult-ivating corn, which employ horizontal share to beams on a plane'with the line of draft, said beams being pivotally attached at their for ward end to pendent hangers attached to the forward portion of the wheel-frame.

The object of the invention is to construct an I5 improved share-holder especially designed for the abovenamed class of share-beams.

A further object consists in an improved construction for attaching the end ofthesharebeams to the hangers.

In the drawings, torming a partof this specification, Figure l is aside elevation; Fig. 2, a plan of details in Fig. 1; Fig. 3, an enlarged perspective of the left-hand end of Fig. 2; Fig. 4, an enlarged perspective of right-hand end of Fig. 2; Fig. 5, a section on line 1 l in Fig. 2, and Fig. 6 is a back view of partD in Fig. 4.

Referring to the letters of reference marked on the drawings,the part B is the share-beam, attached in the below-described manner at its 20 forward end to the lower end of the pendent hanger D. The hanger D is bolted to the forward part of the frame T. The timber extending to the right of the hanger in Fig. 1-is one of the broken converging sides of the tongue,

as ordinarily made in Cultivators, and not here shown. The hanger and share-beam are of course duplicated on the opposite side of the machine, asin corncultivatorsin common use.

In Figs. 4 and 5 is plainly shown the de- 3 vice for attaching the beam to the hanger.

The C-shaped coupling freceives the end of the beam B between its free ends, and is pivoted to the beam by a bolt, so that the coupling f may be swung around the end of the beam to the opposite side. This is done by first removing the nut from the pivotal boltg and detaching the eouplingf from the hanger D. Then when the couplingf is swungto the other side of the beam it is attached by bolt 3 to the other side of the hanger D, for the pur- 5o pose of locating the beams B farther apart, to attach between said beams I3 acenter beam and its share,to convert the machine from a corncultivator to a field-cultivator or sulky-harrow. The center section is not here shown, but being in common use will be understood. This coupling device hasthefunction ofauniversa. joint, allowing the beam B to swing laterally on its pivotal bolt and to tilt vertically with the couplingf on the pivotal bolt y. The end of the hanger D has a series of adjustingholes for bolt y, as in Figs. 5 and 6, so as to change the height of the coupling f.

The share-holder or tooth-holder is clearly shown in Fig. 3. Two metal blocks, rr, have open grooves o in the edge of one side, so that when the blocks are bolted together by the bolt 6, passing through them and the beam B, the grooves 12 register with each other, forming a complete grooveto receive the end of the 73 tooth or share and rigidly hold it by clamping the edges thereof. A lock groove is made in the side of one of the blocks r, at right angles to the share-grooves,to receive the end'of the lock-bar u. The bolt 6 passes throughthe 75 end of this bar. Thus when the bolteis tightened, the share and Ioek-bar,in their peculiar engagement with the blocks 1' v", brace against each other, preventing the blocks from turning and keeping the shares in proper position. 8

In the construction here shown each end of the lock-bar a is employed to lock the blocks of two holders, one holder being forward of the other. i

To locate thesharesin proper positionin this class of cultivators, the rear holder is thrown out farther from the beam by theintervention ot' the thimble (I, through which thimble the bolt 6 also passes. Thus the bar it serves asa brace to bot-h holders (in addition to locking o them) against the draft-strain on the bolt 6.

If only a single holder is used, the bar a may beanchored to the beam atone end, and attached with the holder at the other end. The holder may be employed on other styles of beamsand barrows.

At a a are shown the style of barrow orcul tivator teeth I prefer to use; but they form no part of this invention. per 80, as any style of share may be employed the upper end ofwhich ii adapted to fit the grooves of the holder.

Having thus described my improvements, what I claim is-- t 1. The Combination, with a share-beam and a tooth or share, of a holder consisting of two blocks, each provided with registering sharegrooves in the edges of one side, and one of the blocks having a lock-groovein one side at right angles to the share-groove, a rigidly-held lockbar having one end in the lock-groove, and a clamping bolt attaching the holder to the beam, substantially as set forth.
